Gentlemen. We have an '88 Spanish R4 GTL, with only 40k miles on the clock. Bodily, no rust, and interior very good. We bought it sometime ago with a couple of problems that defeated the previous owner. It had a front bump and needs a bit of bodywork refettleing. There was a problem with a failed head gasket which we have dealt with. The car runs pretty well, but is a bit lumpy. It starts well, but to run it appears to like a little choke, sometimes when you stop, or slow down, and the engine returns to idle , the engine will cut out. We have driven it a bit, hoping that use would make it run better, but it has not. I am in Lichfield, Staffordshire, a bit north of Brum and would like to know if anyone can recommend an R4 specialist who can have a look at the ignition/carburettor set up for me.Thank you.
